为了提高Al2O3陶瓷涂层的综合性能,对陶瓷涂层性能影响因素进行了正交试验设计.以磨损量、结合强度和耐腐蚀性为评价指标,得出了在Al2O3陶瓷颗粒粒径为160目,颗粒填入量为125％,涂层厚度为1mm时,综合性能最好.同时利用差示扫描量热(DSC)技术推算出胶粘剂体系的最佳固化工艺为50℃(1h)→100 ℃(2 h)→225 ℃(1h)；采用磷酸阳极化(PAA)方法对铝合金基体表面进行处理,使其与涂层之间获得最好的结合强度.%To improve the comprehensive performance of A12O3 ceramic coating, orthogonal design was applied to the influencing factors of ceramic coating. Abrasion amount, bonding strength, and corrosion resistance were selected as evaluation index. The results showed that when the size of A12O3 ceramic particle is 160 meshes, fillings of particle is 125%, and thickness of coating is lmm, the coating has the best comprehensive performance. The best cure process of its adhesive system was obtained by using differential scanning calorimetry(DSC) and calculation, which is 50℃(lh)→100℃ (2 h)→225 ℃ (1h); to improve the adhesive strength of coating, the surface of aluminium alloy is treated by phosphoric acid anodizing (PAA).
